For the same to cross-arms a5 and a,.or other convenpurpose of completely insulating the fusible strips and their connected conductors from each other, a plate of ber or other insulating material r2 is placed across the compartment D2, thus preventing an accidental short-circuit being formed. The openings P and S are also preferably constructed with non conducting thimbles p and s, serving to prevent contact between the iron ofthe case and the conductors leading through the openings.

The box or compartment D is in like manner equipped with circuitcontrolling and safety devices, as indicated at g', t, j', and n', connected with the respective terminals of the primary coil, and the primary conductors lead through suitable openings, w', at the bottom of the compartment.

The outer ends ofthe compartments D and D2 are closed securely by glass plates T and T2, respectively, and these are preferably held in position by annular clamps t and t and rubber washers t3 and t". rlhe plates of glass allow the circuit-connections to be inspected without opening` the box. For their better preservation, however, disks a and a2 are preferably fastened in front of the plates in such manner that they may be easily removed or swung aside when desired.

The converter, as shown in the present instance, consists of the two coils P and S, surrounded by plales ofiron, b, the plates being secured together by bolts b b. The converter- .box is constructed to conform in general shape to the converter, and when placed in position the ends of the rods holding'thc plates rest upon the shoulders if and b".

For the purpose of preventing the Wires of the coil from coming into contact with the iron of the case, suitable shields, c and v2, may be made to project over the ends of the coils, such shields constituting hoods formed upon plates V V2, fastened to the ends ofthe core formed by the plates b.

XVe claim as our invention- 1. A converter-box constructed in two sections, the one provided with means for securing it to supports and the other having two separate compartments for receiving the primary and secondary circuit-controlling devices.

2. A converter-box constructed in two parts, the one bei ug provided with separate compartments formed by lateral webs, non-conducting plates within said compartments, and circuitcontrolling devices carried upon said plates.

3. The combination, with a box for containing an electric converter, of two independent compartments integral therewith for receiving the primary and secondary terminals, respectively, non-conducting plates within said compartments, independentcircuitcontrolling devices for the respective primary and the respective secondary conductors carried by said plates, and non-conducting plates between the respective circuit-controlling devices in each compartment. y

4; The combination, with a box for containing au electric converter, ot' independent compartments integral therewith for containing the primary and secondary circuit-controlling devices, and transparent plates closing said compartments.

5. The combination, with a box for containing an electric converter, of independent compartments integral therewith for containing the primary and secondary circuit-controlling devices, transparent plates closing said compartments, and protecting disks outside said plates.

6. rlhe combination, with an electric converter., of supports for the primary and secondary conductors, respectively, and a box containing the converter secured at one end to the support of the primary conductors and at the other end to the support of the secondary conductors.

7. rlhe combination, with an electric converter, of supports for the primary and secondary conductors, respectively, a box containing the converter, secured at one end to the support ofthe primary conductors and at the other end to the support of the secondary conductors, a compartment for receiving the terminals of the primary coils ofthe converter, a second compartment for receiving the terminals ofthe secondary coils of the converter,

and openings at the bottom of the respective compartments for receiving conductors leading to the primary and secondary coils, respectively.

8. The combination, with an electric converter and a box containing the same, of hoods of non-conducting material intervening between the converter-coils and the metal ofthe box, substantially as described.

In testimony whereof we have hereunto subscribed our names this 23d day of March, A. D. 1887.
